Research advances of MAL family members in tumorigenesis and tumor progression (Review)

Abstract

The myelin and lymphocyte protein (Mal) family is a novel gene family first identified and characterized in 2002. This family is comprised of seven members, including Mal, Mal2, plasmolipin, Mall, myeloid differentiation-associated marker (MYadM), MYadMl2 and cMTM8, which are located on different chromosomes. In addition to exhibiting extensive activity during transcytosis, the MAL family plays a vital role in the neurological, digestive, respiratory, genitourinary and other physiological systems. Furthermore, the intimate association between Mal and the pathogenesis, progression and metastasis of malignancies, attributable to several mechanisms such as dna methylation has also been elucidated. In the present review, an overview of the structural and functional properties of the Mal family and the latest research findings regarding the relationship between several MAL members and various cancers is provided. Furthermore, the potential clinical and scientific significance of MAL is discussed and directions for future research are summarized. Contents1. Introduction 2. MAL/VIP17 3. MAL2 4. PLLP/TM4SF11 5.
